Guys, 

I had an error in 3.7.27:
   https://sourceforge.net/tracker/index.php?func=detail&aid=1657247&group_id=23725&atid=379483

I fixed this in 3.7.28.  I also added the feature that the gcc arch defaults
will be used for any gnu compiler, regardless of compiler name (i.e., gcc-4.1
and gcc32 will both use the gcc defaults).  I still have a couple of tweaks
to make configure compiler tweaking easier, as you can see at this feature
request:
   http://sourceforge.net/tracker/index.php?func=detail&aid=1653503&group_id=23725&atid=379485

Note that ATLAS does not presently check for versioning info, so if I build
the arch defaults for the prerelease 4.2 compiler, and you use an old 4.1 
or 3.2, then performance may be depressed.  So, it is important to do a
"make time" step to see if your timings hold up against mine . . .

Cheers,
Clint
